Your PoolMath logs are now showing.

If CYA is 90 or above, do the diluted test as outlined in the article attached.
If you mixed 1/2 poolwater with 1/2 tap water for the diluted test, you would double the CYA result from that test.

Okay so I did the diluted test and cya was 90 possibly 100 (was hard to tell since it wasn't super bright outside. Will test again tomorrow). So does that mean my cya is 180?

If you did as I outlined in post #21 and got a result on the tube of 90, your actual CYA is at least 180.

You can do another diluted test with 2 parts tap water, 1 part pool water and the result is 3 times what you read on the tube.

Best to do the test in the conditions outlined earlier.

Yes i followed the instructions. I appreciate all of your help! I'll re-test tomorrow and them work on draining and refilling over a period to see if I can lower the CYA.

If you CYA is 180+, chances are you will be replacing 70%-80% of your pool water.
Once we know your actual CYA level, we can discuss replacing water options.

It uses less water to exchange it all in one go than to do multiple exchanges.

We suggest using the no drain exchange method (section 3.5)
as its the safest way to replace a large amount of water.

Thank you so much for all the the detailed info! I'm going to read through everything that has been sent. And I just bought more chlorine so I can add it tonight. We had our pool built almost 2 years ago and over the last several months I've really been learning a lot more through this site on how to keep everything maintained.

Absolutely. Do it now.

I have the Taylor K1005 and the FC tube only goes to 5. Is there a different kit I should buy so I can be more accurate with my FC?

Great. Be sure you ordered the K2006 C. The C matters.

The best value are the kits from TFTestkits.net.
